摘要：

We investigate the phase structure of the Z2-symmetric hermitian 3-matrix model. In a double scaling limit exact differential equations for the scaling functions around the critical points are derived. We show that the nonperturbative solutions of all models are described by members of the generalized KdV hierarchies. One of these models, a member of the fourth hierarchy, can be identified with the tricritical Ising model. © 1990.
